Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

  • Win condition: Link Summon and Xyz Summon Cyberse boards (Code Talker / Accesscode / Transcode / Decode Talker links, Primathmech Alembertian and Laplacian) for 2300-ATK link pressure (Inferred from card text).; Going-second disruption: hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Nibiru, Droll & Lock Bird, Evenly Matched) stall the opponent's combo, then Cyberse links close (Inferred).
  • Turn 1 (going first): Search with Cynet Mining / Small World / Backup @Ignister, Normal Summon a Level 4 or lower Cyberse, then build a Link into Accesscode or Transcode Talker. Missing core cards (Accesscode, Transcode, Wicckid) lower the odds of this line (Inferred).
  • Turn 2 (going second): Hold 2-3 hand traps (Ash, Ghost Ogre, Ghost Belle, Droll) to answer the opponent's first combo activation, then Normal Summon a Cyberse starter to rebuild (Inferred).
  • Recovery: Mulcharmy draw effects and the Ghost hand traps recycle cards from the GY and hand. The Link engine is redundant enough to restart after one interruption (Inferred).
  • After siding: Not assessable: the Side Deck is empty, so there is no post-side plan (Verified from evidence).

Why it scores here

The score is driven by the list as a system, not by an average of its card scores. Its consistency comes from 15 searcher-text cards (P of at least one in a 5-card opening hand about 0.81) and a Cyberse base that lets several starters feed each other. Interaction is the strongest area: 12 hand traps and 20 removal-text cards give a 6-card going-second hand a likely answer (about 0.79). The weak points are the lack of recorded boards (no combos, no guides, no tournament data) and an empty Side Deck, so the combo ceiling and median cannot be measured and are inferred from text only. Archetype popularity did not earn points: exact Mathmech purity is only 8.6%, and the Mathmech, Code Talker, Mulcharmy, @Ignister and Firewall pieces are spread across sub-archetypes. The deck is Illegal (3 copies of Ash Blossom against a limit of 2), so the Final Contextual score is capped at 20 and the structural read is theoretical only.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 62 P(at least one searcher-text card in opening 5) about 0.81; P(at least one archetype-core card) about 0.69; Cyberse base 36/55 (Inferred)
D2 Opening-Hand Quality & Brick Management 55 Hand traps and multi-role starters reduce dead hands, but 16 level-0 or non-engine spells and 3-copy redundancy give moderate brick risk (Inferred)
D3 Combo Conversion & Ceiling 45 No recorded boards; ceiling inferred only from text: Link 4-5 and Xyz plus Code Talker and Mathmech links reach 2300-ATK boards (Inferred)
D4 Combo Floor & Median Output 40 No combos_evidence (total_combos 0); median output cannot be measured and is inferred low-moderate (Provisional)
D5 Interruption Resilience & Route Redundancy 55 Several independent starters (Dotscaper, Micro Coder, Backup @Ignister, Mulcharmy draw effects) allow route redundancy after one interruption (Inferred)
D6 Resource Economy, Recovery & Grind 50 Mulcharmy draw effects and Ghost hand traps recycle cards; no resource signature data is available (Inferred)
D7 End-Board & Interaction Quality 68 Interaction density is high: 12 hand traps, 12 negation-text and 20 removal-text cards; no interaction density measurement exists (Inferred)
D8 Going-Second & Board-Breaking Power 65 P(at least one hand trap in going-second hand 6) about 0.79; Ghost and Ash hand traps answer boards (Inferred)
D9 Offensive Pressure & Closing Power 55 Link monsters with 2300 ATK and Primathmech Xyz finishers give closing power; no end-board or win data (Inferred)
D10 Main Deck Efficiency & Flexibility 50 55 main, 34 distinct; 19 singletons and 9 doubles with 3-copy hand traps; compact-enough but mixes sub-archetypes (Verified count, Inferred coherence)
D11 Extra Deck Efficiency & Coverage 55 12 Link and 3 Xyz; 15 Extra slots filled, but Accesscode and Transcode Talker (100% core inclusion) are missing (Verified list, Inferred coverage)
D12 Side Deck Adaptability 10 Side Deck is empty (0 cards), so no adaptability is available (Verified)
D13 Matchup Coverage & Format Fit 50 No tournament link and no dated metagame sample; archetype share is not available (Provisional)
D14 Pilotability & Error Tolerance 35 Link and Code Talker sequencing with hand-trap timing has multiple decision points (Inferred)

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary; the 80/20 Structural/Tournament split is used because Meta is provisional. Structural ≈ 52, Going First ≈ 45, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (over copy limit) (-8); Illegal cap (0). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*52 + 0.20*45 = 51, then the Illegal cap applies (theoretical/structural only) and the final score is set to 20. Modifiers total -8 and are included in the capped result.

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.81 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Dense hand-trap and removal-text package gives a likely answer to a going-second combo (about 0.79 in hand 6).
  • Searcher density (15 cards) gives about 0.81 odds of a starter in a 5-card opening hand.
  • Extra Deck carries high-ATK link and Xyz finishers, including Primathmech Alembertian and Laplacian.

Weaknesses

  • Illegal copy count: 3 Ash Blossom against a limit of 2.
  • Low archetype purity (8.6%) spreads resources across Code Talker, Mulcharmy, @Ignister, Firewall and Salamangreat.
  • Empty Side Deck removes any post-side plan.
  • Core Link pieces (Accesscode Talker, Transcode Talker) are absent from the list.

Critical choke points

  • Starter access depends on Cyberse searchers (Cynet Mining, Small World, Backup @Ignister); a hand without one of them has no clear first Link.
  • Ash Blossom's over-limit copy count makes the list illegal as built.
Priority Remove Add Reason
1 1x Ash Blossom & Joyous Spring any legal card of the deck owner's choice Restores legality: 3 copies exceed the OCG Semi-Limited limit of 2 (Verified). Score cap stays until this is fixed.
2 0 (no change to core) 1-3 Side Deck cards The Side Deck is empty, so there is no post-side adaptability (Verified; Inferred benefit).

Evidence & confidence

  • Verified: Main 55, Extra 15, Side 0 are within OCG size rules (main 40-60, extra 0-15, side 0-15).; Ash Blossom & Joyous Spring: 3 copies vs legal limit 2 (Semi-Limited) makes the deck Illegal.; Mathmech Circular and Droll & Lock Bird run 1 copy each at their Limited limit of 1.; Exact archetype purity is 8.6% (6 of 70 Mathmech-tagged or main copies).
  • Observed: No recorded boards, so no measured combo frequencies exist (total_combos 0).
  • Inferred: Opening-hand odds: searcher group 0.81, archetype core 0.69, hand-trap group in going-second hand 0.79.; Interaction density is high based on 12 hand traps and 20 removal-text cards.; Midrange primary with Toolbox and Combo secondaries, based on hand-trap density and Link engine text.; Structural 52, Tournament reliability 45, and going-first/second splits are derived from text and probability only.
  • Provisional: Meta Power is null: no dated metagame sample and no tournament link.; Matchup and format-fit (D13) score 50 without archetype share data.
  • Data gaps: No combos supplied: the combo floor, median and ceiling are text-only inference. No tournament link: archetype meta-share and per-pilot match record are absent. No win-rate telemetry exists in YGOVN for going-first, going-second, matchup, brick or starter rates. Empty Side Deck: post-side plan cannot be assessed. No guides attached (total_guides 0). Meta Power is provisional unless a dated metagame sample is supplied. Deck title is null in the export.
